CUT-OUT VALVE FOR HYDROCARBON-ENGINES.

Application filed September 10, 1968. Serial No. 452,468.

To (ZZZ whom it may concern Be it known that I, F REI) C. SCHOENTHAL, ofthe city of Buffalo, county of Erie, and State of New York, haveinvented a certain new and useful Cut-Out Valve for Hydrocarbon-Engines,of which the following is a full, clear, and exact description.

My invention relates to a device to be used in connection with two ormore electrodes. spark plugs or other ignition devices and its chiefobject is to provide a means for keeping such electrodes, spark plugs orother igniting devices when any one of them is not in use clean from allsoot. carbon deposits and oil, and also means for protecting theinsulations from the action of the compressed gases. The numerousadvantages besides the above, resulting from the use of my inventionwill be clear to those skilled in the art from the followingdescription.

Referring to the drawings: Figure 1 is a sectional view of my devicefitted into the cylinder of a hydrocarbon engine. Fig. 2 is an endelevation of my device. Fig. 3 is a top plan view of Fig. 2. Fig. 4 isan elevation partly in section of the valve and valve stem. Fig. 5 is atop plan view of my valve. Fig. 6 is a bottom view of the valve.

In the drawings 1 represents the cylinder of a hydrocarbon engine and 2is a plug which as shown in Figs. 1 and 2 has a ground joint or gasketseat so that it fits securely into the cylinder of the engine. It willbe clear that this plug may or may not be an integral part of thecylinder of the engine as desired. Preferably I make such plug aseparate piece from the cylinder and when so made as clearly shown inFigs. 2 and 3 it carries integral with it a strap 3 having lugs 4 and 5overhanging a part of the engine cylinder. Through these lugs aresuitably passed bolts 6 and 7 which are screwthreaded to the cvlinder.

The plug 2 is provided with two or more screw-threaded ignitionportholes 8 and 9 into which spark plugs 10 and 11 may be securelythreaded. In the drawings Ihave shown two such port-holes thus providingfor a double ignition system but it will be clear that any desirednumber of such portholes may be provided depending on the number ofignition systems desiredto be used with the engine. The plug 2 is alsoprovided with a valve stem hole through which the valve stem 12 isadapted to pass. Suitably secured to the valve stem 12 or madeintegrally part thereof, is a valve base 13 which as applied to thedouble ignition system shown in the drawings is provided with threeports 14, 15 and 16 as shown in Fig. 6. A suitable packing 17 isprovided for preventing a leak of gas past the valve stem and thispacking at 18 provides a seat for the spring 19. An opposite seat 20 forthis spring is provided by means of a nut 21 which is screw-threaded asshown in Fig. 1 to the valve stem. The nut 21 may be adjusted up anddown on the valve stem as desired and locked in position by means of thelock nut 22. Of course the tendency of the spring 19 is to draw upwardlythe valve stem 12 and thus hold the valve base 13 upward securelyagainst the plug 2 and thus prevent the compressed gases, soot, oil orother dirt from reaching either one or both of the port-holes 8 and 9 ifthey are covered by the said valve base. In Figs. 5 and 6 where thevalve base 13 is clearly shown I have shown openings 14, 15 and 16 oneor tWo of which when the valve stem is suitably turned by means of thevalve handle 23 will. register with the port-holes 8 and 9 in the plug2. Also when suitably turned the valve base 13 will close either theporthole 8 or the port-hole 9 as desired thus protecting it from anyaccumulating deposits.

The plug 2 may be provided as shown in Fig. 2 with an opening 24 intowhich a priming cup 25 may be inserted. The purpose of this priming cupbeing to provide ingress into the explosive chamber of suitablequantities of gasolene to assist in starting the engine when it hasdifiieult-y in drawing its first fuel supply from the carbureter. anyhyrocarbon engines use two or more ignition systems usually one beingused as the regular system and the other for emergency purposes. In somecases, however. more than two ignition systems are emloyed and of coursewhen so employed my invention is adapted for allowing the use of eitherof the systems employed or only one of them at any one time. It will beseen that the valve base 13 may be rotated so that it will tightly closeeither one of the port-holes 8 or 9 and thus when only one of the sparkplugs 10 and 11 is used the other may be entirely protected from anyaccumulating deposits and thus the spark plug be kept clean andprevented from deterioration. Obviously the holes. 14, 15 and 16 may berelatively located in any desired way so that either one of theport-holes 8 or 9 may be closed or if more port-holes are employed andmore spark plugs used, then any one of the port-holes in the plug 2 maybe kept closed to the interior of the explosive chamber of the engine asdesired.

It will be clear that various modifications in the shape and generalconformations of my device may be employed without departing from thespirit of the invention or the advantages secured by it. Thus as alreadystated the plug 2 may be made integral with or separate from the enginecylinder. The strap 3 may be employed as shown or some other means forkeeping the plug 2 in proper relation with the cylinder may be employedwith as advantageous results as attained by the use of the strap asshown. It will be likewise understood that the valve base 13 althoughshown as circular in its interior surface may be equallyadvantageous-When made as a tubular, flat or sliding valve base. Anyform of valve base which will tightly close as desired one or moreof thespark plug port-holesand keep it closed, or open it when desired, willobviously attain most of the advantages attained by means of thespecific construction herein shown.

Of course it is understood that my invention is not limited to theprecise construction set forth but includes within its purview suchchanges as may be made within the limits of the appended claims.

What I claim is:

1. In a hydrocarbon engine, the combination with a. cylinder, providedwith ignition port holes arranged in any desired manner and extendingdirectly into said cylinder and spark plugs fitted into said port holes:of a. cut-out valve rotatably mounted in said cylinder, comprising avalve stem and a valve. base disposed within said cylinder and governingall of said ignition port holes, said valve base being provided withopenings so placed that one or more of said openings may be registeredwith a corresponding number of said port holes or any one of said portholes may be shut off from said cylinder thus cutting olithe explosivemixture from the spark plug fitted therein and protecting the same fromthe accumulation of soot and also allowing its removal if desired.

2. In a hydrocarbon engine, the combination with a cylinder, providedwith ignition port holes arranged in any desired manner and extendingdirectly into said cylinder and spark plugs fitted into said port holes;

of a cut-out valve rotatably mounted insaid cylinder, comprising a valvestem and a valve base disposed within said cylinder and governing all ofsaid ignition port holes, and

means for rotating said valve base, said ofl the explosive mixtures fromthe spark plug fitted therein and protecting the same from theaccumulation of soot and also allowing its removal if desired.

3. In a hydrocarbon engine, the combination with its cylinder; of a plugset in substantially flush with the inside of said cylinder and providedwith ignition port holes arranged in any desired manner and whichconverge inwardly toward each other, spark plugs adapted to fit in saidport holes, and a cut-out valve rotatably mounted in said plug,comprising a valve stem and a valve base governing all of said portholes and provided with openings so placed that one or more of saidopenings may be registered with a corresponding numbenof said port holesorany one of said port holes may be shut off from said cylinder thuscutting off the explosive mixture 'from the spark plug fitted thereinand protecting the same from the accumulation of soot and also allowingits removal if desired.

4. in a hydrocarbon engine, the combination with its cylinder; of a plugset in substantially flush with the inside of said cylinder and providedwith ignition port holes arranged in any desired manner and whichconverge inwardly toward each other, spark plugs adapted to fit in saidport holes, and a cut-out valve rotatably mounted in said plug,comprising a valve stem and a valve base governing all of said portholes, flexible means for holding said valve base tightly against theinner surface of said plug, and means adjustably secured to said valvestem, said valve base being provided with openings so placed that one ormore of said openings may be registered with a corresponding number ofsaid port holes or any one of said port holes may be shut off from saidcylinder thus cutting off the explosive mixture from the spark plugfitted therein and protecting the same from the accumulation of soot andalso allowing its removal if desired.
